Aerosol Backscatter

The article briefly describes an optical probe for direct measurements and studies of the vertical distribution of the aerosol component of the atmosphere. The operation principle is based on the measurement of backscattering from a sequence of powerful probing pulses. The analyzed air volume is located at a close (0.5 m) distance from the radiation source. LEDs at 470 nm and 940 nm are used as radiation sources. The probe can be easily integrated with all types of standard aerological radiosondes, meteorological rockets, and having its own navigation module and telemetry system it can also be used in autonomous launches. The results of measurements carried out at the Dolgoprudny aerological station in November 2020, which recorded low values of the aerosol backscattering coefficients in the stratosphere, are presented.

AbstractSurface melting of High Mountain Asian debris-covered glaciers shapes the seasonal water supply to millions of people. This melt is strongly influenced by the spatially variable thickness of the supraglacial debris layer, which is itself partially controlled by englacial debris concentration and melt-out. Here, we present measurements of deep englacial debris concentrations from debris-covered Khumbu Glacier, Nepal, based on four borehole optical televiewer logs, each up to 150 m long. The mean borehole englacial debris content is ≤ 0.7% by volume in the glacier’s mid-to-upper ablation area, and increases to 6.4% by volume near the terminus. These concentrations are higher than those reported for other valley glaciers, although those measurements relate to discrete samples while our approach yields a continuous depth profile. The vertical distribution of englacial debris increases with depth, but is also highly variable, which will complicate predictions of future rates of surface melt and debris exhumation at such glaciers.
